Won't this cause BTI to be forced off for static binaries?

Perhaps this should be (has_interp == is_interp), as for
arch_elf_adjust_prot().  Seems gross though, since has_interp would
become useless after the next patch.  If there's no sensible way to
keep this bisectable, perhaps the patches can be merged instead.

Ugh, right.  I only tested the finished result.
